Manga Lucky Star is pretty popular in Japan! The manga's characters play video games, and Lucky Star itself has already gotten a couple of DS games as well as a PlayStation 2 visual novel. Nerds love Lucky Star. Probably why the owner of this Osaka "delivery health" shop (think outcall call girl business) decided to use characters Kagami and Miyuki. Also, Kagami is a fan of shooting games — as in video game shooting games. Ah, nevermind.
